(E)-3-(2-Nitrophenyl)-1-{1-phenylsulfonyl-2-[(phenylsulfonyl)methyl]-1H-indol-3-yl}prop-2-en-1-one

In the title compound, C30H22N2O7S2, the configuration about the propene C=C bond is E. The indole unit is essentially planar, with a maximum deviation of 0.031 (3) Å. The dihedral angle between the planes of the phenyl rings of the two phenylsulfonyl groups is 80.95 (19)°. The central prop-2-ene-1-one group is oriented at a dihedral angle of 44.26 (11)° with respect to the nitrophenyl ring and at 39.24 (8)° with respect to the indole unit. The S atoms are in a distorted tetrahedral configuration. In the crystal, molecules are linked into centrosymmetric dimers via pairs of C—H⋯O hydrogen bonds with an R 2 2(24) graph-set motif. The crystal structure is stabilized by further C—H⋯O interactions. Short intramolecular C—H⋯O contacts result in several S(6) rings.

In the title compound ( Fig. 1), the indole moiety is essentially planar with a maximum deviation of 0.031 (3)Å for the atom C6. The configuration of the keto group with respect to the olefinic double bond is typically S-cis, with O5-C22-C23-C24 torsion angle -18.1 (4)°. The propenone group exhibits an E configuration with respect to the C23═C24 double bond.
The indole moiety, is perpendicular to both the nitro phenyl ring and the phenylsulfonyl ring, bonded to the N atom of the indole ring system with interplanar angles 81.04 (11) and 89.21 (14)°, respectively. The methyl substituted phenylsulfonyl ring is inclined with respect to the indole moiety and the phenylsulfonyl ring, bonded to N atom of the indole ring system at angles of 9.01 (16)° and 80.95 (19)°. The two sulfonyl bound phenyl rings make a dihedral angle of 73.17 (17)° and 52.35 (15)° with the nitro phenyl ring. The nitro-group is inclined at an angle of 27.63 (16)° with the benzene ring, to which it is attached.
The molecular dimensions in the title compound are in excellent agreement with the corresponding molecular dimensions reported in closely related compounds (Varghese et al., 1986;Seetharaman & Rajan, 1995).
The crystal packing is stabilized by intermolecular C-H···O interactions and molecules are stacked along the a axis; the molecules are linked into centrosymmetric dimers via pairs of C-H···O hydrogen bonds with an R 2 2 (24) graph-set motif (Bernstein, et al., 1995) (Fig. 2). Intramolecular C-H···O hydrogen bonds generate S(6) ring motifs.
